Syntax
SET PARSEONLY { ON | OFF }
[ ; ]
Remarks
When SET PARSEONLY is ON, SQL Server only parses the statement. When SET PARSEONLY is OFF, SQL Server compiles and executes the statement.
The setting of SET PARSEONLY is set at parse time and not at execute or run time.
Don't use PARSEONLY in a stored procedure or a trigger. SET PARSEONLY returns offsets if the OFFSETS option is ON and no errors occur.
